TO ALL WHOM IT MAY CONCERN:

Be it known that I, R. M. GANO,-of Allegheny City, in the county of Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in Brick-Machines; and Ida hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, I will proceed to describe it.

My invention consists in a novel and simple construction of amachine for mixin bricks at the same time, as hereinafter explained.

Figure 1 is a. top plan view.

Figure 2 is an elevation, with the side broken away, to show the interior.

1 construct a pug-mill, consisting of a. box, A, having a shaft, 0, with wings or arms, d, attached thereto, and projecting radially, said arms being turned obliquely edgewise, so as to act as a screw, and press the clay downward as the shaft is rotated. At the bottom of the box A. an opening, u, is made, to permit the clay to pass out, a spout, E, being connected to the box at that point, and extending out over a circular table, B, placed in front of the box A, and mounted on a frame attached thereto, as shown in fig. 2. This table B rests on friction-rollers, m, and is provided with aseries of moulds or openings, of proper size and form, to mould the clay into bricks, these moulds being so located as to pass under the spout E, as the table revolves, and receive a supply of clay from the spout as they pass from under it. These moulds are each provided with u follower or block a, whichslides loosely up and down therein, they having a stem, 0, attached to their lower side, and resting on an inclined circular track, T, which is so arranged that when the moulds are under the mouth of the spout E, the followers shall drop down in the mould, below the surface of the table, a. distance equal to the thickness of the brick, in which position they remain while the brick is being pressed, after which they are gradually raised by their stem 0 passingup the inclined track T, until the brick is shoved out of the mould, when they again descend, ready to receive a fresh charge of clay, as they pass under the spout E.

The pressing is done by a. heavy roller, C, which is arranged to rest and revolve'on the surface of the table B, as shown in fig. 2, a frame, n, pivoted to the box A, serving to hold the roller in position at the mouth of the spout E, which it just fits loosely, and where it presses or rolls over each mould successively, as they pass from under the spout filled with clay. The weight of the roller, which should be about four hundred pounds, prevents-the clay from passing out of the spout, except when a mould arrives in position to receive it,

g the clay and pressing after which it rolls over the mould and presses it down flush with the top of the modlds, finishing the brick in a very smooth and nice manner. A wheel, G, secured to the top of shaft C, gears into a similar whccl, II, on shaft I, of the table B, by which both are made to move together.

Having thus described my invention, what I claim, is-

The pressure-roller 0, arranged to operate. in combination with the rotating table, provided with a series of moulds for forming bricks, substantially as described.
